FERNDALE, Calif. (CBS/AP) — The U.S. Geological Survey is reporting an earthquake with a preliminary magnitude of 5.3 off the coast of northern California.
The USGS says the quake was centered in the Pacific Ocean, about 70 miles west of Ferndale, California, and struck about 4:16 a.m. PST Thursday. The quake was later downgraded to magnitude 5.1.
Ferndale is located just over 100 miles south of the Oregon state line and about 275 miles northwest of Sacramento.
An officer with the Ferndale City Police Department said some slight shaking was felt in the area early Thursday. He said no damage or injuries were reported.
The earthquake was about 250 miles northwest of the epicenter of a magnitude 6.0 temblor that caused extensive damage in Napa and the surrounding area on Aug. 24.
